Distributed Software Transactional Memory (D-STM) promises to alleviate difficulties with lock-based (distributed) synchronization and object performance bottlenecks in distributed systems. Past Single Copy data-flow (SC) D-STM proposals keeps only one writable copy of each object in the system and are not fault-tolerant in the presence of network node/link failures in large-scale distributed systems. In this paper, the authors propose a Quorum-based Replication (QR) D-STM model, which provides provable fault-tolerant property without incurring high communication overhead compared with SC model.
